Replaced master window control on 2009 lexus rx 350. Programed worked fine for

What is your question?

A few days now windows are getting stuck open half way etc. have to use the other window controls drivers only works when it wants and window lock worked initially now won't engage. I contacted the place I bought it from and they sent me a new one. The same thing happened with the new one within a few days including the window lock. It will work perfect at first.

Nothing
